PHPGurukul Art Gallery Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Art Gallery Management System version 1.1. The issue resides in the file '/admin/changeimage1.php', where the 'editid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, with the injected SQL code executed without proper input validation or sanitization, potentially leading to unauthorized database access and data manipulation.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, with possible impacts including unauthorized data access, data modification or deletion, and in some cases, executing commands on the server under the database user's privileges.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/changeimage1.php' with the 'editid' parameter. The request can include a payload that exploits the SQL injection, such as a boolean-based blind injection or a UNION-based injection that extracts data from the database.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions can also help reduce the impact of such vulnerabilities.
